There aren't any players at Kansas making those kind of dollars in NIL. As of February, the total dollar amount of all athletes in all sports COMBINED was only around $500k.
Here's KU's report on the status of NIL deals as of February:
In the seven months since the NCAA made profiting on one’s name, image and likeness legal, athletes at the University of Kansas have cashed in on close to half a million dollars. KU Athletic Director Travis Goff on Thursday morning provided an update on KU’s NIL statistics to the Kansas...

"In it, Goff said more than 80 different Jayhawks have brokered more than 170 total NIL deals since July 1 through the end of January. In addition, Goff said at least one athlete from all 17 of KU’s varsity sports had received an NIL opportunity and that the average transaction value per deal was $2,728.
“(That’s) heavily skewed by maybe the handful of five-figure men’s basketball deals,” Goff added. “Nothing in the six figures. Nothing that I think has been just at the forefront of progressive, so to speak, but we feel good having created a foundation of education with a strong lens toward compliance.”"
I am sure those numbers will go up after the barnstorming tour by the KU basketball team over the next month or so where the players get a portion of ticket sales as they tour small Kansas towns doing exhibitions etc... but no single basketball player is getting even close to $500k-$1 million.
